Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed February 19, 1918. Serial No. 218,082.

To all whom it may concern:

Be it known that I, PINKNEY P. FRAZER, a citizen of the United States of America, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Bearings, of which the following is a specification.

This invention relates has for its and effective means whereby a bearing may be quickly tightened when it becomes necessary to compensate for the wear of the Babbitt metal or other like substance with which bearings are commonly lined.

In the accompanying drawing, where like numerals refer to like parts throughout the several views, Figure 1 is'a top plan View of the complete improved bearing shown in connection with an emery wheel or other like tool the shaft of which projects therethrough; Fig. 2 a top plan View with the Fig. 1.

upper brass of the bearing removed and in- Verted, so as to expose the interior arrangement; Fig. 3 a vertical longitudinal section taken along line 3-3 of Fig. 1; and Fig. 4 an end elevation taken along line 4-4 of In carrying this invention into practice I provide inclined slots 1 and 2 in the lower brass 3 of a conventional type of bearing and insert therein wedge-shaped keys 4 and 5 which are best'shown .in Fig. 3, the upper edge of each key being formed with a lug 6 and these lugs projecting through openings 7 and 8 provided in the flanges 9 and 10 of the upper brass 11.

Assuming that the brasses have been newly lined and the parts are being assembled, it will be appreciated that keys 4 and 5 are driven inward to substantially their full length as shown in Fig. 3 so that when the upper brass 11 is positionedits flanges 9 and 10 will rest upon the upper edge of said keys with the result that its bushing (71. e. its Babbitt lining) from the bushing of the lower brass 3 to the'extent of approximately a quarter-inch as best shown in Fig. 4.

to bearings and. object the provision of simple is separated Thereafter, when the lining has been worn by the friction of shaft 12and it becomes necessary to alter the original adjustment so as to tighten the bearing, set-screws 13 are loosened and keys 4 and 5 driven outwardly to a slight extent by tapping upon lugs 6 so as to permit the top brass to descend to an extent sufiicient tocompensate for the wear, whereupon said screws are turned inwardly to retain said keys intheir new location and the brasses are secured together by tightening nuts 14 upon bolts 15- which project from the base of standard 16.

From the foregoing it will be clear that the application of this invention is not limited to any particular tool or class of machines and that, in addition to other uses, it will be found of distinct value in line shafti'ng where it is of prime importance to effect necessary repairs as rapidly as possible, and the right is reserved of making such changes in the form and proportion of the several elements as experience may determine without departing from the spirit of the invention or the scope of the following claims.

What I claim as new and desire to secure by Letters-Patent is-: l. A bearing comprising a lower brass having inclined slots formed therein, keys disposedv in said slots substantially corresponding to the formation thereof, a detachable brass disposed over said keys and supported thereby, and meansfor connecting said brasses.

2. A bearing comprising a lower brass having inclined slots formed therein, keys disposed in said slots substantially corre- 1 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, WashingtoinlLO."
